REGISTERING DEVICE.

HPECIFECATION forming part of Letters Patent No. 342,388, dated May 25,1886.

Application tiled September i, 1855. Serial No. 176,155.

To (tZZ whom it may concern.-

Be it known that LL. LEwIs SAGENDORPH, of the city of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Registering Devices, of which the following is aspecification.

My device is an index to be attached to an engine or machine to indicatethe number of revolutions or complete movements made by the machine.

In the accompanying drawings, Figure l is a rear elevation of my device.Fig. 2 is an elevation as seen from the 1eft-hand side of Fig. 1. Fig. 3is an elevation of the operatingratebct with attached mechanism. Fig. 4is a front elevation of the indicatouface. Fig. 5 illustratesparticularly the functions of the adj ustable'arm H.

Two standards, A, mounted on a suitable base-plate, support themechanism. These standards are cut away and grooved to receivethejournal-blocks B. The shaft B is journaled in the blocks B, andprojects beyond each standard A. A toothed wheel, 0, pref erably ofconsiderable width, is shrunk onto the shaft B, or otherwise rigidlyattached there to. 011 each side of the wheel 0 is a bar, E, one ofwhich bars may be dispensed with; but the arrangement shown ispreferred. These bars E are slipped onto the shaft B and retate looselythereon. Blocks E are placed between the corresponding ends of thesebars E to keep them far enough apart to prevent fric- 3 5 tion againstthe wheel 0.

Screws or bolts S pass through the bars E and blocks E binding themtogether, and make a frame which rotates or oscillates on the shaft I3about the wheel G. The pawl P,

mounted on the shaft P, (see Fig. 3,) engages the teeth of the wheel 0,and is kept against these teeth by the spring K. The preferredattachment of the spring K to the shaft P is very simple and efiicient.A slit, P is made across the end of the shaft 1? at right angles to theline of the pawl 1 In this slit P the straight spring K is secured, andit is then bent around over the pin or lug P. This gives it the requiredtension.

The bar E is attached to lower ends of the chine.

(No model.)

bars E,and its lower end being placed between them takes the place of ormay be connected to a rigid extension of the lower block E. A bar, H,passes through the end of the bar E, and is seen red there by theset-screw S for the purpose of setting the rod H and regulating therapidity of the rotation of the dial-plate, and the number of notchesthe wheel 0 is rotated at each throw or movement of the ma- A spring, V,is attached to the lower end of the bar E, and also to some otherconvenient point. It acts to draw the pawl I? back, as shown in Fig. 1.

\Vhere journal-boxes O are present, each standard A is respectivelyprovided with a separate cap. B placed across the top of each standard,and the screws S secure their respective caps B to their respectivestandards. Through each cap B a bolt, S, passes and bearsagainstthebearing-block,\vl1ich it serves to keep in place. Vhendesircd,the journalboxes B may be dispensed with, and thejour nals ofshaft B work in openings in the solid plate.

At the rear of the device is a frictionclutch, G. This clutch ispreferably made of a single piece of metal split through nearly itsentire length, and provided with enlargements and openings toaccommodate the screw S and the end of the shaft B. The clutch is firmlyattached to the standard A by the screw S a washer, w, intervening. Itthen clasps the shaft B and the amount of pressure or friction which itexerts on the said shaft in opposition to the rotation of said shaft isregulated by the screw S The indicator disk or plateD is centered on thefront end of the shaft '13, and rigidly secured thereto, so that it mayturn with the shaft.

An indicator or index hand or pointer, I, is attached to the base-plateM, or other fixed part of the machine, and projects in front of the diskD. This pointer indicates the amount of movement of the disk I).

The mode of operation is very simple and almost apparent from the deviceitself. The device is attached to the engine or machine, so that somepart of the moving machinery, preferably a pin on a wheel, may strikethe IOC arm H. When the rod His struck, it brings the bars E E into theposition shown in Fig.

, 3. With this movementthe pawl P turns the bythe indicator I on thedisk D. When a single disk D is insufficient to represent the desiredrevolutions of the machine, this disk may be geared with a series ofdisks in the usual or any desired manner, either on its periphery or onthe shaft, so that the various disks may represent units, tens,hundreds, 850.

The advantages of the adjustability of the arm II will be apparent fromFig. 5,where the arm H is shown in connection with a cam or rotarymovement on the machine. N indicates a cam or disk fixed to a shaftrotating in stationary bearings. A lug, W, is fixed on the disk or cam,or,when the disk or cam rotates in a strap or yoke, the lug W may be.

affixed to said strap or yoke. Each rotation of the cam causes lug \V tomove the arm H forward and the registering-disk to be rotated, the armbeing then immediately drawn back into position to be again moved by thelug W.

While the arm H occupies the position shown in solid lines in Fig. 5,the lug W will cause arm H to rotate the disk one digit. If, now,thearmH be lowered and reset by means of setscrew S in the position shownin dotted lines in Fig. 5, the lug \/V will move the arm H fart-her, andcause the pawl P to skip a greater number of teeth of the wheel 0, and

cause the disk D to be rotated more than one digit. In this manner thenumber of digits to be registered at each movement of the machine can beregulated. In some classes of machines it may require some intermediatemechanism to specially adapt this arm H to the machinery to beregistered, and in some instances it may be desirable to dispense witharm H and allow the arm or piece E to be moved directly by the machinewhose movements are to be registered.

WVhile the various features of my invention 5 are preferably usedtogether, one or more may be used without the remainder, and, in so faras applicable, in connection with registering devices other than the oneherein specifically set forth. 6o

\Vhat I claim as new and of my invention, and desire to secure byLetters Patent, is

1. The combination of shaft B, wheel 0, bar E, pawl P, standard A, andsplit frictionclutch G, provided with clamping-screw S substantially asand for the purposes specified.

2. The combination of standard A,shaft B, toothed wheel 0, bars E, pawlP, spring K, bar E, and split friction-clutch G, provided with theclamping-screw S substantially as and for the purposes specified.

8. The combination of standards A, provided with bearing-blocks B, shaftB, toothed wheel 0, bars E, pawl P, spring K, bar's E, spring V, clutchG, disk D, and indicator I, substantially as and for the purposesspecified.

4. The combination of shaft B, wheel 0, pawl P, bar E, shaft P, providedwith slit P, and spring K, one of whose ends is located in said slit P,pin or lug P against which the spring bears and by which it is put intension, substantially as and for the purposes specified.
